Embodiment Construction

[0019] The technical solutions of the present invention will be further described below in conjunction with specific preferred embodiments.

[0020] A high-impact, reinforced, flame-retardant and aging-resistant PC and PET blended gold. Its components are proportioned by mass percentage: PC 48%, PET 20%, methacrylate-butadiene-benzene with core-shell structure Ethylene copolymer (MBS) 5%, nano barium sulfate 10% activated by silane coupling agent KH550, melamine polyphosphate 10%, light stabilizer 2%, polymethyl methacrylate grafted maleic anhydride ( PMMA-g-MAH) 3.5%, antioxidant 0.5%, pentaerythritol stearate (PETS) 1%. Wherein, the PC is a bisphenol A type aromatic polycarbonate with a weight average molecular weight of 20,000 to 40,000 g / mol; the PET is polyethylene terephthalate with an intrinsic viscosity of 0.6 to 1.0 dL / g; The light stabilizer is a compound of hindered amine high molecular weight light stabilizers GW-944Z and GW-622 with a mass ratio of 1:1; the antioxi...

Abstract

The invention discloses a high-impact resistant reinforced flame-retardant and ageing-resistant PC and PET blend alloy. The blend alloy comprises the following components in percentage by mass: 30%-60% of PC, 10%-30% of PET, 3%-8% of an impact-resistant modifier, 5%-10% of a fortifier, 5%-10% of a flame retardant, 0.5%-2% of a light stabilizer, 2%-5% of a compatilizer, 0.1%-0.5% of antioxygen and 0.5%-1.5% of a lubricant. The blend alloy disclosed by the invention has the beneficial effects that compared with the prior art, the PET flame-retardant ageing resistant parent material is firstly prepared, and then the PC and PET blend alloy is prepared by modifying PC with the parent material, the added impact-resistant modifier and the fortifier, and the PC and PET blend alloy has the respective excellent performance of the PC and the PET, has the advantages of high impact-resistance, good mechanical performance, high strength, good flame-retardance and ageing resistance, and has very good prospect on the aspects of household appliances, automobiles, instruments and meters, electrommunication and the like.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a blend of high-impact, reinforced, flame-retardant and anti-aging PC and PET. Background technique [0002] Polycarbonate (PC) is a type of polymer containing carbonate in the molecular chain. It has excellent transparency, mechanical strength, and thermal stability. It is one of the five general engineering plastics. Its products and consumption are second only to nylon Engineering plastics rank second, but PC has the disadvantages of high melt viscosity, difficult molding and processing, and not resistant to oil and solvents. Polyethylene terephthalate (PET) is a semi-crystalline material, which has very good chemical stability, mechanical strength, electrical insulation properties and thermal stability, especially oil resistance and solvent resistance. However, PET alone has disadvantages such as poor heat resistance and low impact strength. Blending PC and PET can obt...
